Three-Dimensional Channel Modeling and Analysis of Electromagnetic Field for WiFi

As wireless networks become more and more popular, people are paying more attention to the question of whether WiFi signals are harmful to the human body. In this paper, a full 3D propagation model based on ray tracing and uniform diffraction theory is used to predict the electromagnetic radiation environment of indoor 2.4 GHz WiFi signals. The electromagnetic distribution of the ground and the wall of office in the study area are effectively calculated. The research content can provide a basis for further wireless channel modeling and electromagnetic situation research.
